Real-time construction worker posture analysis for ergonomics training

Construction activities performed by workers are usually repetitive and physically demanding. Execution of such tasks in awkward postures can strain their body parts and can result in fatigue, injuries or in severe cases permanent disabilities. The number of reported cases every year is in the thousands. Among these injuries, back injuries and Work-related Musculoskeletal Disorder (WMSD) are the most common injuries. Such injuries occur primarily with workers involved in carrying heavy loads, kneeling, contact stress, vibration, extreme temperatures, twisting hands or wrists, stretching to work overhead or other awkward positions while performing job activities. These injuries typically occur due to awkward work posture while carrying out tasks such as lifting loads (back and knee injuries) and working overhead (neck and shoulder injuries).
